A rookie fourth-round pick, Spiller is competing with Joshua Kelley and Larry Rountree III to be Austin Ekeler’s primary backup.
After carrying a team-high 10 times for 34 yards in the preseason opener, Spiller had his night Saturday cut short by an ankle injury.
After the game, coach Brandon Staley said the Chargers had yet to determine the severity of the injury, but he did say it “should not be anything serious.”
Still, like most rookies, Spiller needs all the snaps he can get and any time missed will set him back in his bid to be an immediate contributor.
Kelley has started the first two preseason games, suggesting he’s first in line at the moment behind Ekeler.
